// TODO:
//   (1) Figure out why error productions dont work.  `type-declaration' is a
//       great spot to put an `error' because you can reproduce it with this input:
//	 "public X { }"
//
// Possible optimization:
//   Run memory profiler with parsing only, and consider dropping 
//   arraylists where not needed.   Some pieces can use linked lists.
